Problem with receiving SNMPv3 traps with authentication

[AGENTPP]

Yes, the following sentence should be part of every SNMPv3 FAQ:

@AGENTPP

Please make sure Agent and Manager have different engine IDs.

The first sentence of the following quote is not correct, because the trap sender is authoritative. Thus, the engineID relevant for the authenticity is the engine ID of the sender (= authoritativeEngineID in UsmParameters of the SNMPv3 ScopedPDU). The second part about the need of incrementing the engineBoots counter on each restart (=reset of the egineTime) is true:

@MichTar

I will include the receiver’s local engineId in the sent trap, and engineBoot incremented after each receiver restart for a given fixed receiver engineId.
